[0001] The present invention relates to the field of liquid crystal display technology, and in particular to a novel liquid crystal display module with excellent heat dissipation effect. Background Art

[0002] In modern society, liquid crystal display technology has been widely used. Liquid crystal display modules have many advantages such as thin body and power saving, and are widely used in devices such as handheld computers, computer screens and notebook screens. In the existing technology, the LED light bar is placed on the inner side of the back panel, and the heat of the LED light bar is dissipated by heat conduction. The outer frame and the rubber frame cooperate to fix the liquid crystal display panel. When the LED light bar is working, a large amount of heat will be generated. This heat is concentrated on the inner side of the back panel and is difficult to dissipate effectively. Continuous high temperature will not only affect the normal operation of the light bar, but also easily cause the light guide plate to expand due to heat, seriously affecting the overall use effect and life of the liquid crystal display module. Therefore, there is still a lot of room for improvement in the display module. Summary of the invention

[0015] Figure 2 for Figure 1 A is a partial enlarged view. DETAILED DESCRIPTION

[0016] Reference Figure 1 and Figure 2 As shown, a novel liquid crystal display module with excellent heat dissipation effect proposed by the present invention includes a back plate 1, a reflective sheet 2, a light guide plate 3, an optical film material 4, a rubber frame 5, a liquid crystal display panel 6, an outer frame 7, a heat conduction block 8, an LED light bar 9, a dust blocking plate 10 and a plurality of screws 11;

[0017] The reflective sheet 2 is installed on the back plate 1, the light guide plate 3 is arranged above the reflective sheet 2, the optical film material 4 is arranged above the light guide plate 3, the rubber frame 5 is sleeved on the back plate 1, the liquid crystal display panel 6 is installed on the rubber frame 5 and is located above the optical film material 4, the outer frame 7 is sleeved on the rubber frame 5, the heat conducting block 8 is installed between the side of the back plate 1 and the rubber frame 5, and a light conducting through hole 101 is provided on the side of the back plate 1 at a position corresponding to the light guide plate 3; the heat conducting block 8 is provided with a mounting groove at a position corresponding to the light conducting through hole 101, and the LED light strip 9 is installed in the mounting groove; the heat conducting block 8 is provided with a heat dissipation groove 81 connected to the lower space thereof, and the heat conducting block 8 is located in the heat dissipation groove 81 and a plurality of heat conducting columns 82 are installed.

[0018] In this embodiment, a heat dissipation ring 83 is sleeved on the heat-conducting column 82, and the heat dissipation ring 83 can further improve the heat dissipation effect of the present invention.

[0019] In the present embodiment, an insulating pipe 84 is installed on the heat conductive block 8, and the insulating pipe 84 connects the lower space of the heat conductive block 8 with the heat dissipation groove 81. The heat in the heat dissipation groove 81 is discharged through the groove. The insulating pipe 84 can replenish cold air for the heat dissipation groove 81 to realize air circulation, which greatly improves the overall heat dissipation effect of the present invention. The insulating pipe 84 is connected to the bottom of the heat dissipation groove 81, which is conducive to further improving the heat dissipation effect of the present invention.

[0020] In the present embodiment, the two opposite sides of the dust blocking plate 10 are respectively connected to the back plate 1 and the rubber frame 5. The dust blocking plate 10 is located below the heat conductive block 8. A plurality of ventilation holes are provided on the dust blocking plate 10. The dust blocking plate can prevent the user's body from directly touching the heat conductive block 8, and can keep the heat conductive block 8 clean to a certain extent, and reduce the influence of dust on the heat dissipation performance of the heat conductive block 8. The cross-sectional area of ​​the ventilation hole gradually decreases from top to bottom, which can reduce the possibility of dust falling on the heat conductive block 8 and can be beneficial to the air flow near the dust blocking plate 10.

[0021] During the operation of the present invention, the LED light bar 9 will generate a large amount of heat. Since the LED light bar 9 is installed on the outside of the back plate 1, the heat accumulated in the back plate 1 can be greatly reduced compared with the prior art, thereby reducing the requirements for the thermal conductivity of the back plate 1. The heat generated by the LED light bar 9 will be transferred to the heat conductive block 8. The heat conductive block 8 can increase the heat dissipation area through the heat dissipation groove 81. The heat conductive column 82 improves the stability of the present invention and further improves the heat dissipation performance of the present invention. The overall volume of the present invention does not change much, but the overall heat dissipation performance is greatly improved. In this embodiment, the heat insulating pipe 84 is located on the side of the heat dissipation groove 81 away from the LED light bar 9, which can not only reduce the influence of the heat insulating pipe 84 on the thermal conductivity of the heat conductive block 8, but also help to keep the heat conductive block 8 at a low temperature. The back plate 1, the LED light bar 9, the heat conductive block 8, the rubber frame 5 and the outer frame 7 are fixed by screws 11. The screws 11 are easy to manufacture and easy to disassemble, and compared with the outer frame 7 being fastened to the back plate 1, the difficulty of manufacturing the back plate can be greatly reduced, and the manufacturing cost can be saved.
